SPECIFICATION forming part of Letters Patent No. 450,079, dated April'7, 1891.

Application filed m 28, 1888.

To all whom it may concern: 4

Be it known that I, EDMUND JORDAN, a citizen of the United States, .andresident of Brooklyn, in the county of Kings and State of New York, haveinvented certain new and useful Improvements in a Combination of Diesfor Use in a Machine for Making Barbed Strips, of which the following isa specification. 1

This invention consistsof improved contrivances of dies for producingtwo barbed strips from one blank strip by slitting a plain flat blankstrip of metal which is equal in width to two barb-strips to be madeplus the breadth of the barbs by intermittent slits which offset in anoblique line from one plane to another and so overlap that the offsetline of each slit crosses from the plane of one part of the slit to thatof the other between and in close proximity to the ends of the nextslits each way, by which bars from which to form barbs are separatedalong their edges from the two strips, which are also nearly separatedby the same means from eachvother; but said bars remain connected at theends to the respective strips and are subsequently separated obliquelyat the middle to point them and effect the complete separation of thestrips, and then the barbs so formed are bent laterally to the stripsfor causing them to project as required, thus making onelaterallyprojecting barb alternately on each strip; but for making twosimilarly-projecting barbs together on each strip alternately, which isthe preferable way, the said overlapping slits are made longer, withgreater distance between the offset lines and the ends of the next slitseach way, and other slits are made in prolongation of the parallelportions of said slits each way across the offset line, so that twobarbs are made thereat besides the two others from the bars subsequentlyseparated, and thus two barbs are formed together on each stripintermediately, and they are likewise bent for lateral projection, ashereinafter fully described.

In the drawings, Figure 1 represents face views of said slitting andbar-cutting dies and of one each of two pairs of bending-dies forbending the barbs. Fig. 2 represents a side elevation of the dies forslitting the blank Serial No. 281,313. (NomodeL) 'strip and cutting thebars to make two barbs alternately on each strip, together with thebending-dies and a blank strip between the dies. Fig. 3 is a diagram ofthe blank strip, showing the action of the dies of Figs. 1 and 2 on it.Fig. 4 is a side elevation of the dies for making single barbs on eachstrip alternately. Fig. 5 is a diagram of the blank strip, showing theaction of the dies of Figs. land =6 on it. Fig. 6 represents face viewsof the slitting and bar-cutting dies and of one each of thebending-dies, as in Fig. 4.

f' I make slitting-dies f g, as shown, to make interval slits b 0 dinthe blank strip a, the part jobeing an oblique offset from b to d, whichare in different parallel planes as wide apart as the desired width ofthe barbs and being at the middle of the slit. When the barbs are to bein the single order along the strips, the slits are advanced along thestrip a dis- .tance equal to the distance the barbs are to :be apart onthe finished strips, as in Fig. 5, and the length of the slits is inthis case such that being so advanced the distance fromoifset 0 of oneslit, to the beginning of the next slit is the length of metal left at 6connecting the barbs at the base with the strips, which may be more orless, as preferred, being vagried as the slits are made longer orshorter; but it is designed to have ample metal thereat to formsubstantial connection of thebarbs. The length of the barbs is governedby the length of the slits, the slits being made longer for longer barbsor shorter for shorter ones; but where two barbs are to be formedtogether on each strip intermediately the slits b c d are made longerand are also advanced along the strip relatively to each other thelength of a barb more than in the other case, as represented in Fig. 3.For making these slits dies f g are employed, which are alike in formfor both cases, but differin length, and the strip is to be fed thelength of two barbs in one case and of four in the other. It proceeds inthe former case to the bar-cutting dies h i, by which the bars madebetween parts I) and d of the successive slits are cut apart at q, andbarbs s are formed; but in the latter case it is next presented totheparallel-edged slittingdies j k,whereby the slits Zare made inprolongation of lines I) d across offset line 0, making two barbsthereat, and also-to the bar-cutters h 1', which at the same time outapart the bar made between the slits and form two other barbs. From thebar-cutters the next feedshift presents the barbs ready for bending tothe bending-dies m n and 0 19, arranged in two pairs for bending thebarbs laterally to the strips and alternately in. opposite directions,said dies consisting of male and female members suitably contrived forso bending the.

barbs, as clearly represented in the drawings. In the making of fourbarbs to one feed-shift, as in Figs. 1, 2, and 3, both pairs of thesebending-dies will operate contemporaneously with the rest; but in theother arrangement for making only two barbs to one feed-shift these dieswill only act with each alternate tially the same as in the method whichisthe subject of the patent granted to me March 17, 1885, No. 314,183,and are not broadly claimed herein, in which I have contrived to utilizethat plan of cutting together with the cutting of the bars to separateandpoint the barbs and with bending devices which makelaterally-projecting barbs, all operative together with the cutting-diesto "complete the cutting, separating, and bending in one operation.Suitable guides will be provided for preventing the out parts of theblank from spreading under the influence ofg'the dies.

The method herein described} is reserved for a separate application fora patent.

What I claim, and desire to secure by Let ters Patent, is j 1. Thecombination of dies, asfg, having the cutting-edge offset in an obliqueline at the middle, or thereabout, and arranged for making intervaloffset overlapping slits, and 5 the diagonal bar-cutting dies, as h 2',arranged with said slitting-dies for successively cutting the bars madeby them, substantially as described.

2. The combination of dies, as f 9, having the cutting-edge ofiset in anoblique line at the middle, or thereabout, and arranged for makinginterval offset overlapping slits, the

diagonal bar'cutting dies, as h 2', arranged with said slitting-dies forsuccessively cutting the bars made by them, and the barbbending dies, asm n and 0 p, arranged with said slitting and bar-cutting dies for successivelybendin g the barbs cut by them laterally to the strips,substantially as described.

3. The combination of dies, as f g, having the cutting-edge offset in anoblique line at the middle, or thereabout, and arranged for makinginterval offset overlapping slits, also the paralleledged slitting-dies,as j 70, arranged with said oifset slitting-dies for successivelycutting other slits each way from the diagonalcuts in prolongation ofthe parallel portions of the offset slits, and also the diagonalbar-cutting dies, as 7i 1', arranged for successively cutting the barsformed by the offset slitting-dies, substantially as described.

4. The combination of (lies, as f 9, having 'the cutting-edge offset inan oblique line at agonal bar-cutting dies h 71, arranged forsuccessively cutting the bars formed by the offset slitting-dies, andalso the barb-bending dies, as m n and 0 90, arranged with said slittingand bar-cutting dies for successively bending the barbs cut by themlaterally to the strip, substantially as described.
